Twitter being a monopoly but Facebook not would be totally ridiculous in more than one way.

EDIT: Just to be clear I'm not saying your post is ridiculous, but Trump is. And yes the following is somewhat sarcasm END EDIT.

Let me guess next Mercedes and BMW have a oligopol on cars and china will be classified as a company with an monopol on cheap products.

The crazy/scary think is that I believe Trump would totally cable of doing it if he get's the legal power and time to do so...
